		we use the build-in, the following will be an issue and a potential solution.
		
		Every time we turn off/on the robot, these encoders will read 0 and the absolute encoder will read the real value.
		I didn't do it here, but we will need a function that moves all the turn motors so that their positions are set to what
		the absolute encoder says it is. Something like
		for index, encoder in enumerate(self.turnEncoders):
			encoder.setPosition(self.absoluteEncoders[index]%360)
		because I've been using an unhealthy amount of for loops this reason. This would allow the auto to go from there, although
		the motors should have been zeroed beforehand. There would be a similar function that can be ran in teleop when a sufficiently
		out-of-the-way button is pressed so that we can automatically reset the motors to 0 when in the pits, something like
		for index, encoder in enumerate(self.turnEncoders):
			encoder.setPosition(self.absoluteEncoders[index]%360)
			self.turnControllers[index].setReference(0, rev.controlType.kPosition)
		that of course then removes itself from the queue once all four motor encoders are at 0 and all the absolute encoders are at 0.
		Despite a reset being available in the pits, we would still need to set the motor encoders to the absolute encoder positions
		to account for possible bumping, absent-minded turning, or in case we didn't have time to return to the pits and so were only
		able to reset the wheel positions by hand'''
